The Bangladesh Institute of Nuclear Agriculture (BINA) has developed two new Aman rice varieties named 'BINA Dhan-27' and 'BINA Dhan-28', marking a new milestone in the country’s rice research. The varieties were officially approved for nationwide cultivation at the 115th meeting of the National Seed Board held at the Ministry of Agriculture. With these additions, BINA’s total number of developed rice varieties has reached 28.

'BINA Dhan-27' is the country’s first high-yielding Aman rice resistant to blast disease, incorporating two effective resistance genes, Pi9 and Pish. The variety grows 95–100 centimeters tall, resists lodging in strong winds, and yields six to 6.5 tons per hectare on average, reaching up to seven tons under favorable conditions. 'BINA Dhan-28' is a zinc-enriched, aromatic, medium-slender rice developed through marker-assisted backcrossing, containing 24.83 milligrams of zinc per kilogram.

Researchers said 'BINA Dhan-28' matures in 120–125 days, yields about 6.5 tons per hectare, and produces fluffy, tasty rice with 27.42% amylose content. BINA officials believe these varieties will enhance farmers’ income, improve nutritional security, and reduce production costs.
